420 Countdown

A live countdown to 4:20 PM — every day, on the dot, in your own time zone. We're not going to pretend to know why this exact minute has such a devoted global following. We just kept getting asked, so we built the countdown. What you do when it hits zero is entirely up to you.

Counts down to 4:20 PM, your local time.

Why is 4:20 such a big deal?

Couldn't tell you. We looked into it and came away dazed and confused — and somehow always ended up looking through the fridge. We're told it's a very relaxing part of the day.

Using this at work?

Maybe not the best idea — but we've got your back. Hit the Boss! button and the countdown vanishes, replaced by a very boring spreadsheet. You're welcome.

Once a year, it's 4/20 at 4:20

April 20th is the main event — the one day of the year the whole 420 community counts down together. Every 4/20, the date and the clock line up at exactly 4:20 PM. We built a countdown to 4/20 so you're ready for the big day.
